But that's exactly what happened when the late swap meet mogul and multi-millionaire Preston Henn, a car enthusiast, wanted to add a LaFerrari Spider to his fleet of cars in 2016.

As seen on a recent episode of CNBC's "The Filthy Rich Guide," Henn ran into a rich-guy roadblock while trying to add the vehicle to his lot: Customers can't just purchase the $1.4 million sports car — they need a personal invitation to buy. No matter how rich that customer might be.

So when Henn placed an order for the exclusive Ferrari, he was rejected. Apparently being a millionaire many times over wasn't good enough.

That didn't stop Henn, however. He wrote a letter to the company, disputing the verdict and explaining that he had previously owned 18 Ferraris. He also enclosed a check for $1 million.

Ferrari promptly denied him and returned the deposit.

What's a scorned millionaire to do? He sued the car manufacturer for $75,000, claiming that Ferrari had damaged his reputation as a collector. However, the suit was later dropped.

And although Henn passed away in April, never having owned a LaFerrari Spider, his Ferrari collection lives on — some speculate one of his cars could be the most valuable in the world. If Henn's 1964 Ferrari 275 GTB/C Speciale, one of only three of its kind, makes it way to auction, it could be the first car ever to fetch $100 million.
